Comparative Study of Lipid and Fatty Acid Profile in Liver Tissues of Male and Female Silurus triostegus During the Catching Seasons

In this study, seasonal variations of total fatty acid (FA), phospholipid (PL) and triacylglycerol (TAG) compositions in liver tissues catfish (Silurus triostegus) were investigated. Samples S. triostegus obtained from Atatürk Dam Lake, Turkey, two month periods during one year as May. The major components palmitic (16:0), stearic (18:0), oleic (18:1n-9), palmitoleic (16:1n-7), docosahexaenoic (DHA, 22:6n-3) arachidonic (AA, 20:4n-6) lipid, 16:0, 18:0, 18:1n-9, eicosapentaenoic (EPA, 20:5n-3), DHA AA PL, 16:1n7, linoleic (LA, 18:2n-6), AA, EPA, docosapentaenoic (22:5n-3) TAG extracted the all seasons. N-3/n-6 ratio was found 2.00-2.61 females, 1.15-2.75 males lipid. highest lipid content May (2.39%) females. males, level September (2.91%). fraction, component with lowest both sexes’ is PUFA. PL SFA, MUFA, PUFA percentages at similar rates sexes months.
